[mapserver-users] Raster does not accept expression values

[Gabriel Messner]

I have a Float32 raster, which was made with Arcgis Spatial Analyst. When
retrieving it with mapserver using different Class with Expression values,
nothing appears, but with just one Class the raster is shown right in a gray
scale palette.

Any help would be appreciated.
